Unless there is some other topic about this option, I was thinking about

In

`Properties > Security > Groups or authenticated users`

I have 4 entries:

1] Authenticated Users

2] SYSTEM

3] Administrators (NAME-OF-MY-MACHINE\Administrators )

4] Users ((NAME-OF-MY-MACHINE\Users)  
` `  
` `  
The `1` lacks for files `Full control` while the `4` lacks `Full control`, `Modify` and `Special permissions`. But changing these to `Allow` does not help- Mp3tag still behaves in the same way [I have that file format o the list and yet I do not see such files in the main window]
